Section 4 Verifying Operation
1. When using the H8/36049 group E6000 emulator (HS3664EPI61H), turn on the emulator
according to the procedures described in the H8/300H Group E6000 Emulator User's Manual
(HS300HEPI61HE).
2. Verify the user system interface cable connections by accessing ports and checking the bus
states of the pins. If an error is detected, recheck the soldered IC socket and the location of pin
1.
3. The emulator connected to this user system interface cable supports two kinds of clock sources:
an emulator internal clock and an external clock on the user system, for the MCU clock and
subclock. For details, refer to the H8/36049 Group E6000 Emulator Supplementary
Information (HS3664EPI61HE).
 To use the emulator internal clock
Select the clock in the emulator station as the system clock (φ), by using the CLOCK
command (emulator command).
 To use the external clock on the user system as the system clock
Select target clock t with the CLOCK command (emulator command). Supply the external
clock from the user system to the emulator by inputting the external clock from the OSC1
terminal on the cable head or connecting a crystal oscillator to the OSC1 and OSC2
terminals. When a crystal oscillator is inserted into the OSC1 and OSC2 terminals for the
system clock, the clock is generated by the oscillator circuits shown in figure 10. To input
an external clock from the user system, input clock pulses satisfying the specifications
described in the MCU hardware manual into the OSC1 terminal. The system clock (φ)
frequency is the same as the external clock frequency.
 To use the external clock on the user system as the subclock
Select target clock sub t with the CLOCK command (emulator command). Supply the
external clock from the user system to the emulator by inputting the external clock from the
X1 terminal on the cable head or connecting a crystal oscillator to the X1 and X2 terminals.
When a crystal oscillator is inserted into the X1 and X2 terminals for the subclock, the
clock is generated by the oscillator circuits shown in figure 10. To input an external clock
from the user system, input clock pulses satisfying the specifications described in the MCU
hardware manual into the X1 terminal. The subclock (φw) frequency is the same as the
external clock frequency.
